If any NATO member country invokes Article 5 of the North Atlantic Treaty at any time between November 5, 2025 and December 31, 2026, 11:59 PM ET, this market will resolve to "Yes". Otherwise, this market will resolve to "No". The primary resolution source for this market will be official information from NATO (nato.int), however a consensus of credible media will also suffice.Trader consensus prices "No" at 86.5% for NATO Article 5 invocation before 2027, driven by the treaty's high threshold requiring an "armed attack" on a member state—a bar met only once historically after 9/11—with no such incidents despite Russia-Ukraine war tensions. Recent Polish Prime Minister Tusk's April 24 warning of potential Russian strikes on NATO's eastern flank, including Poland and the Baltics, has not led to verifiable military actions triggering collective defense, echoing NATO Secretary General Rutte's March 5 dismissal of Article 5 over an Iranian missile downed near Turkey. Russia's forces remain stretched in Ukraine, limiting escalation risks to NATO territory, while hybrid threats like sabotage fall short of invocation criteria amid alliance deterrence buildup.
